Application led October 4, 1916.

To all whom t may concern:

Be it known that I, Josnri-T P. TREeo, J r., a citizen of the UnitedStates, residing at Newton, in the county of Harvey and State of Kansas,have invented certain new and useful Improvements in Explosion-Engines,of which the following is a specification.

This invention relates to internal combustion engines and particularlyto means for adapting such engines to the use of a heavier explosivethan gasolene, and has for its object` to provide means whereby thewaste heat of the engine is conserved and used for heating a fuel suchas kerosene oil and adapting it for use in the engine instead ofgasolene.

Another object of the invention is to provide means whereby the heat ofthe explosive gases passing from the cylinder to the exhaust pipe iscaused to raise the temperature of incoming kerosene oil to such a pointthat it will be in condition to form a suitable fuel for the engine whenit enters the cylinder accompanied by sufficient air to form anexplosive mixture.

Another object of the invention is to so arrange the fuel feedingmechanism that either gasolene or kerosene oil may be employed in theengine, and in practice gasolene is used to start the engine andcontinues to operate it until the parts become thoroughly heated, afterwhich the kerosene is substituted and thus enables the engine to bedriven at far less expense than when gasolene is used.

With the above as the principal object in view, the invention consistsof the novel construction, combination and arrangement of partshereinafter described, pointed out in the appended claim and illustratedin the accompanying drawings in which:

Figure 1 is an elevation of an internal combustion engine viewed fromthe cylinder end with the improved attachment for feeding heavyhydrocarbon thereto.

Fig. 2 is a side elevation of the same parts, and

Fig. 8 is a detail sectional view on the line 3 3 of Fig. 1.

In the drawings, 10 indicates the cylinder end of an internal combustionengine in outline upon the top of which is shown mounted a tank 11 forwater. 12 is the inlet pipe for the combustible mixture feeding to thecylinder 10 and 13 is an exhaust pipe through Speccaton of LettersPatent.

which the heated and'consumed gases pass from the cylinder. A pipe 14leads from the gasolene tank and past a regulating valve 15 `into themixer 16, said pipe having a cut-of valve 17 when it is desired towholly shut off the flow of gasolene to the engine. A second pipe 18extends from a tank containing kerosene oil and approaching the exhaustpipe 13 where it leaves the cylinder, is there connected to a pipe coil19 closely surrounding the exhaust pipe 13 for a greater or lesserdistance in the length thereof. The opposite end of the coil 19 isconnected by means of a pipe 20 having a cutoil' valve 21 therein withthe regulating valve 15. For the purpose of retaining the heat of theexhaust pipe around the coil 19, the latter is inclosed with one or morelayers of asbestos 22 and over the asbestos is placed a jacket of sheetmetal 23. There is thus formed a casing through which passes an exhaustpipe 13 as the heating medium for the kerosene coil 19. Perforations 40of small size are made in the exhaust pipe within said casing throughwhich the heated gases may pass directly into contact to the coil 19 andthus more quickly raise the temperature of the kerosene passingtherethrough.

Just below the coil 19 the exhaust pipe 13 is covered by a second jacket24 that extends for a greater or lesser distance along said pipe and isspaced therefrom to form an air passage 25 between its outer wall andthe exhaust pipe 13. The ends of the jacket 24 are closed as at 26 and27 through the latter of which is formed a curved inlet opening 28 forthe entrance of air within the jacket and from thence through a pipe 29to the mixer 16 where air combining with the gasolene or with thekerosene forms an explosive mixture for the engine. To regulate thequantity of air passing into the inlet opening 28, there is provided agate valve 30 of the curved shapem shown in Fig. 3 and having a handle31 by. which the gate may be manipulated. The gate is pivoted at 32opposite the end from which the handle projects on the end 27 of thejacket 24 and by means of the handle said gate may be moved to entirelyclose the inletl opening 28, open it to full extent or to any degreedesired, as is evident.

It is sometimes desirable to feed water into the cylinder with theexplosive mixture and for this purpose there is a pipe 33 connected tothe tank 11 containing water, the outer end of said pipe turningdownwardly and provided with a cut-oill Valve 34 below which is a sightfeed cup 35 from which a pipe 36 extends downwardly suiciently far toConnect with a branch 37 leading to the mixer 16. A drain Cook 38terminates the lower end of the pipe 36 and a similar oook 39 is placedon the kerosene pipe 2O above the coil 19. By adjusting the valve 34,water will drip through the sight feed eup at any rate desired and passthence down into the mixer and with the air and gasolene or keroseneinto the cylinder.

In starting the engine, the valve 17 is opened and gasolene through thepipe 14 used until the engine gets thoroughly heated, after which thevalve 17 is Closedy and the Valve 2l opened permitting the kerosene toflow through the pipe 1S, coil 19 and pipe 20 into the mixer. Thekerosene which was in the coil 19 is, by this time, thoroughly heated bythe exhaust from the combustion of gasolene and upon opening the Valve21 the kerosene is in condition to form a suitable explosive mixturewhieh being fed slowly into the cylinder, passes with equal slownessthrough the coil 19 and so become thoroughly heated by the exhaustigases. The air valve 80 will of course be opened and closed to regulatethe inflow of air in the same manner as is done on all internalcombustion engines. If water is desired with the fuel, the valve 34 willbe opened and being convenientI may be closed at any time.

vWhat is claimed is:

In an explosive engine, the combination with a cylinder having inlet andoutlet pipes, a jacket inolosing the latter, a mixer connected to theinlet to the cylinder, a plu` rality of fuel pipes leading to saidmixer, one of them having a Coil disposed within said jacket, said eoil`fitting closely about said outlet pipe, said outlet pipe havingopenings therein in alinement with the convolutions of said coil,whereby said coil will hold the gases from escaping into the jacket,although allowing the heat thereof to be directly imparted to the coil,for the purposes speciied.

In testimony whereof I affix my signature in presence of two witnesses.
